The lines between Marketing and Public Relations can sometimes be blurred, and as a Marketing Communications Manager, you may be asked to perform tasks that lean more onto the PR side.
Someone who works in public relations will help a business or person build a positive relationship in the public eye by organizing their branding efforts. As a Marketer, you likely take on tasks like this as well. Discuss with the interviewer any experience you have working on a PR objective.
"I have worked on many branding projects geared to improving the reputation of a company after a media scandal, and also individual products after unsuccessful launches. I have worked with the PR department many times, in my current company, as well as engaged with external PR agencies. I believe that PR and Marketing often collide and it's important for me to understand many public relations approaches and techniques."
"I come from the school of thought that public relations and marketing are often of the same goal; this is to exude a positive image of a product, person, or company. I have collaborated with PR professionals on controversial political campaigns as well as business launches gone awry. To be able to blend PR and Marketing is an especially important skill in marketing, today."
